Cannot log in to public open Wifi connection

Solution 1:

Here is what I have found works for forcing the captive portal (i.e., login page for WIFI connections on public hotspots):

1. Make the connection to the WIFI.

2. Open a terminal and type route. You should receive a display such as:

   Kernel IP routing table
   Destination     Gateway         Genmask         Flags Metric Ref    Use Iface    
   default         10.1.0.1        0.0.0.0         UG    600    0        0 wlo1    
   10.1.0.0        *               255.255.248.0   U     600    0        0 wlo1    
   link-local      *               255.255.0.0     U     1000   0        0 wlo1```
   

3. Type the default Gateway (i.e., 10.1.0.1) into your browser's address bar, you will receive the WIFI login page.

I have the same problem and I am going to add the following to my /etc/NetworkManager/NetworkManager.conf file:

[connectivity]
uri=http://nmcheck.gnome.org/check_network_status.txt

Solution 3:

For me,

sudo dpkg-reconfigure resolvconf

completely solved the problem. I hope it will help you.
